Abstract

A strength of a machined cage for a cylindrical roller bearing is increased without reducing a bearing life. An integral machined cage for a cylindrical roller bearing includes: a pair of side plates (42, 44); a plurality of columns (46), which are arranged in a circumferential direction, for connecting the pair of side plates (42, 44); pockets (48) formed between the adjacent columns (46); and relief portions (50) provided at four corners of each of the pockets (48), in which as viewed from a section perpendicular to an axis of the cage, the columns (46) have side surfaces each constituting a circular arc shape, and the relief portions (50) are in parallel to the side surfaces of the columns (46).
